Cal 30-2 Mast and boom dimentions

While sailing Dolsinea Cal30-2 hull#120 on Lake Erie June 6th. at aprox. 10.15pm in 30 to 40 knot breze and 6ft.chop and gaining rapidly on a 40ft yawl I chose to duck under her as we had plenty of speed, just as we strted under her both boats were hit with a sudden wind sheer estemated between65 and 85mph. The 40 footers mast came within 8 to 10 ft. of us and I had no room to round up needless to say we were nocked on our ass all the way to the windows.The main is history, the#2 is history,The boom has a new design and the headsail track is probably history but we wont know till we get the 3piece jib to let go of the track. Mast is coming down for inspection and to remove the 3 piece jib.Now for the meat of this post, I need the correct mast hight and boom length and original black band measurements because I think ours have been altered and I may need to buy a used main till a new one can be made and we have another race in 2weeks.PS old Cals should be named Timex(they take a licking and keep on ticking)
